Once upon a time, two brands met at a party and eventually fell in love with each other. It was a match made in heaven. One was really good at making the best face masks in the world while the other one was the best at making technical apparel. One thong led to another and 9 1/2 months later, they had beautiful babies... Airhole x 686 is born. Get smart and replace that cotton underlayer with the Airhole Thermal Top, a hooded, moisture wicking piece that is sure to become a mainstay of your shred wardrobe.
